Selecting the right chalk art mediums for your project can be a difficult decision. Finding a quality product with the right surface is important. Because of the variety of chalk art mediums, it is important to determine if the substrate you are using is porous or nonporous.

Choose from nine sizes and five color combinations of the country craft framed chalkboards and chalk art mediums. Sizes offered are 8x10, 9x12, 11x14, 16x20, 18x24, 20x24, 22x28, 24x30, and 24x36. Colors include black, blue, green, red, and cherry. Contact us if you unable to find your desired style.

Porous Versus Nonporous

Porous surfaces allow the passing through of water, liquid, or vapor. Pigment from the markers could get absorbed when using porous chalkboards. These types of surfaces include chalkboard painted surfaces, wood, paper, and cardboard.

Nonporous surfaces will not absorb water and liquids. Nonporous surfaces like chalkboard labels, mirrors, glass, glazed ceramic, slate, metals, laminates, and some plastics, will result in liquid chalk being easier to remove.

Therefore, always test your liquid chalk markers on a small portion of your medium to see if they are right for your project.

Creative Project Ideas and Unique Mediums

DIY Christmas Ornaments using Zig Posterman Waterproof Markers

Our artists at Cohas.com are always trying to use the Cohas Color Collection for fun projects.  The latest project involved drawing on clear plastic ornaments with the 1mm waterproof metallic gold and white markers. The flecks in the metallic paint sparkled in the lights of the tree and are nice and opaque.

Additionally, one of our artists used a metallic marker and painted on one side of a piece of acrylic glass.  The result is a colorful shiny background that can be easily cleaned with Windex.  Artists can also use spray paint to complete the same effect on the back, but that would create a more permanent background on your mediumPaint markers used on clear plastic to create a wedding favor.

Finally, Cohas offers chalk artists a wide variety of chalk mediums to create chalk artwork on. This includes our chalkboard label collection, magnet collection, slate and novelty collection, and much more.  For that reason, Cohas.com offers a large selection of wet erase menu board markers, and waterproof chalk markers.  These markers work great for chalk artist.  No doubt Cohas.com has what you are looking for.

Not artistic? You can always grab standard household objects or even items from around the office to trace with your Zig Posterman Paint Markers.  Working on a video about how different marker types are cleaned off a white board surface staff members in the studio got thinking.  What could we use for a paint marker template?

Well it is Christmas Time!

One was an artist Kris, classically trained in the arts but normally does computer artwork today.  Much of the artwork on the website are her design, we hope you enjoy them.

Drawing some circles freehand, the picture of Cohas has lots of circles in it eyes, nose, and the mouth.  We asked Jacklynn to do a circle, Jacklynn is an author and does programming for Cohas.com.  She created the predecessor Zig Posterman Marker website.  Much more at home coding eCommerce websites however, not thrilled with drawing pictures.

Note how Kris is using a paper towel, spraying Expo white board cleaner on the towel to do a neat job cleaning. She was trying to avoid removing the Cohas Cartoon logo drawn on the same white board.

Kris came up with the idea to trace a CD to make a nice clean circle, so off she went to demonstrate.  The first try smeared when she pulled up the disk.  Since the shoot was for “how to remove” Paint Markers from a white board we had some Expo White Board cleaner on hand.  Off went the Circles both hand drawn and with the CD.

Orange Zig Posterman Marker held in a woman's hand with a red grunge shirt filling in a orange Christmas treeThis time she lifted the disk a little more carefully and left a fine lined clean circle. Off to the prop cabinet we came up with a Christmas tree cookie cutter for a paint marker template. This time it was Jacklynn’s turn to create the chalk art tree.  She started out tracing the inside, but it quickly became clear that would not work so well.  So she drew a line on the outside of the cutter.  No problems with clean up.  Just use window cleaner to remove the Zig Posterman Paint from the cookie cutter after it is dry.

Filling in the tree, she was quite proud of her work, until we mentioned that trees are not typically orange this time of year but green.

Next Step?

Grab some Zig Posterman markers along with some everyday household items and start your designs today! Pick a window, counter top, whiteboard, blackboard or any surface that will not soak the ink in.  You will always be able to remove it with an ammonia based cleaner.

Available in nine sizes, these semi-permanent Markers will mark any non-porous surface and will not come off in the rain or when washed. They only come off with a glass cleaner.  Zig Posterman waterproof markers are not like a standard wet erase marker that comes off with water or a damp cloth.  The application of paint markers that are waterproof can be removed with any cleaner that has a pH of 10 or higher.

The ammonia in glass cleaner has that high pH thus required for removal, until you use that type of cleaner your design will not rub or wash off.

  • Glass
  • Plastic
  • Metal
  • Stone
  • Acrylic
  • Coroplast
  • Ceramic
  • Mirrors
  • Blackboard
  • Whiteboard

The large ones are used by law enforcement and the auto industry to mark car windows. Also called Wet-Wipe markers by some, they are similar to Dry Erase Markers but can not be removed once dry by wiping. Used on signs in stores on boards windows these markers allow a restaurant or store to show different messages when required. They are great tools to test out marketing ideas.

Zig Posterman also available as Wet-Wipe markers, be sure you select the right type. Wet-Wipe markers can be removed with a damp cloth or sponge.   To learn more visit these information pages.

How Application of Paint Markers work

The waterproof markers use a quick drying liquid paste similar to a pigment based paint. It can not be removed with a whiteboard eraser. The key component for removal is an ammonia based product. We have found with some of our customers can not remove the image from the boards after they mark them. In all cases it has been that the glass cleaner they were using was “green” or organic based cleaner good for the environment. In those situations, using a Windex type product with ammonia removed the marker, even after attempting to use the wrong cleaning product.

The contents in the fluid are a water base with resin and titanium dioxide (color pigment) the paste is less likely to cause allergic reaction than dry-erase markers with alcohol or chalk dust.

Dry erase markers use an alcohol base that can be removed with a paper towel, rubbing or with a whiteboard eraser. Good for indoor use they are not recommended for outdoor use, like Zig Posterman waterproof markers are.

Application Extra!

Zig Posterman Waterproof  Markers can be used on a dry erase board, they make a semi permanent image that can be drawn over with dry erase markers. When removing the dry erase with an eraser, the Wet Erase image stays on the board until removed with an ammonia based cleaner.

Applications include charts and graphs with text that is changed on a more regular basis.  Another use is the management of manufacturing processes.  By using Zig Posterman markers the data stays on the board until the operator wants it removed!

Dry Erase cleaning fluid is compatible with Zig Posterman markers it will remove all dry erase marks and Zig Posterman marks and any residue left.  Your white board will look like new after you clean it.  Please note, some dry erase markers may be harder to clean than the Zig Posterman paint marker from a white board surface.

Looking for a marker you can wipe off with a dry eraser or a soft cloth from your whiteboard or blackboard?  Try our Zig Posterman Wet-Wipe markers, when dry they will come off any quality board that has a smooth surface just like dry erase markers!

Application of Paint Markers on Chalkboard Painted Surfaces

We do not recommend that Zig Posterman or any pigmented paint marker be used on a a surface painted with chalkboard paint.   These surfaces and the surface painted on tend to be porous this will leave a ghost or permanent mark.

Some customers have been successful using the markers on chalkboard paint.  The subsurface on those items tend to be non porous like metal, plastic, steel, Masonite or glass.  You should test the surface in a inconspicuous area before extensive use.

A better option for the application of paint markers is our Chalkflex chalkboard product available in framed, unframed, as sheets or on a roll for your project.  This stiff but easy to install flexible plastic chalkboard will not stain under normal use.
